BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum x morifolium, typically grown as a cut flower Chrysanthemum and hereinafter referred to by the name ‘DLFEVID1’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program is to create new cut flower Chrysanthemum plants with numerous attractive inflorescences.

The new Chrysanthemum plant originated from a cross-pollination in November, 2016 of a proprietary selection of Chrysanthemum x morifolium identified as code number DB 49894, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum x morifolium identified as code number DB 58765, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Maasdijk, The Netherlands in September, 2017.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings since September, 2017 in a controlled greenhouse environment in Maasdijk, The Netherlands, has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DLFEVID1’. These characteristics in combination distinguish ‘DLFEVID1’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright plant habit; uniform growth habit.     -   2. Dark green-colored leaves.     -   3. Uniform flowering habit.     -   4. Strong upright flowering stems.     -   5. Dense pompon-type inflorescences with numerous white-colored         ray florets.     -   6. Relatively tolerant to high and low production temperatures.     -   7. Resistant to Fusarium (Fusarium oxysporum) and White Rust         (Puccinia horiana).     -   8. Good postproduction longevity.

Plants of the new Chrysanthemum differ primarily from plants of the female parent selection in inflorescence size as plants of the new Chrysanthemum have larger inflorescences than plants of the female parent selection. In addition, plants of the new Chrysanthemum have slightly lighter green-colored leaves than plants of the female parent selection.

Plants of the new Chrysanthemum differ primarily from plants of the male parent selection in inflorescence type as plants of the new Chrysanthemum have pompon-type inflorescences whereas plants of the male parent have incurved-type inflorescences. In addition, leaves of plants of the new Chrysanthemum have fewer leaf margin indentations than leaves of plants of the male parent selection.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum X morifolium ‘DLFSIB1’, not patented. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘DLFSIB1’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum have larger inflorescences         than plants of ‘DLFSIB1 ’.     -   2. Ray florets of plants of the new Chrysanthemum have obtuse to         emarginate apices whereas ray florets of plants of ‘DLFSIB1’         have rounded apices.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph at the top of the sheet (FIG. 1) comprises a side perspective view of a typical flowering stein of ‘DLFEVID1’ grown as a disbud-type cut flower.

The photograph at the bottom of the sheet (FIG. 2) is a close-up view of upper (left) and lower (right) surfaces of typical inflorescences (top of figure) and typical leaves (bottom of figure) of ‘DLFEVID1’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn in ground beds in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial cut Chrysanthemum production. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. During the production of the plants, day temperatures ranged from 18° C. to 25° C., night temperatures ranged from 20° C. to 22° C. and light levels averaged 8 klux. Plants were grown as single-stein disbud-type plants and were nine weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
